Examples

An error message:

swal("Oops!", "Something went wrong!", "error")

A warning message, with a function attached to the confirm message:

• Using promises:

swal({
  title: "Are you sure?",
  text: "Are you sure that you want to leave this page?",
  icon: "warning",
  dangerMode: true,
})
.then(willDelete => {
  if (willDelete) {
    swal("Deleted!", "Your imaginary file has been deleted!", "success");
  }
});

• Using async/await:

const willDelete = await swal({
  title: "Are you sure?",
  text: "Are you sure that you want to delete this file?",
  icon: "warning",
  dangerMode: true,
})

if (willDelete) {
  swal("Deleted!", "Your imaginary file has been deleted!", "success");
}

A prompt modal, where the user's input is logged:

• Using promises:

swal("Type something:", {
  content: "input",
})
.then((value) => {
  swal(`You typed: ${value}`);
})

• Using async/await:

const value = await swal("Type something:", {
  content: "input",
})

swal(`You typed: ${value}`);

In combination with Fetch:

• Using promises:

swal({
  text: 'Wanna log some information about Bulbasaur?',
  button: {
    text: "Search!",
    closeModal: false,
  },
})
.then(willSearch => {
  if (willSearch) {
    return fetch(`http://pokeapi.co/api/v2/pokemon/1`)
  }
})
.then(result => result.json())
.then(json => console.log(json))
.catch(err => {
  swal("Oops!", "Seems like we couldn't fetch the info", "error")
})

• Using async/await:

const willSearch = await swal({
  text: 'Wanna log some information about Bulbasaur?',
  button: {
    text: "Search!",
    closeModal: false,
  },
})

if (willSearch) {
  try {
    const result = await fetch(`http://pokeapi.co/api/v2/pokemon/1`)
    const json = await result.json()
